IMPROVEMENT IN FLOOD-FENCES.

Specification forming part of Letters Patent N0. 1 39,418, dated May 27,1873; application filed November 14, 1872.

To all whom it may concern:

Be it known that I, AUSTIN ORVIS, of Ellington, in the county of Hancockand State of Iowa, have invented a Flood-Fence, of which the followingis a specification:

The invention relates to that class of fences which pass across streamsliable to be flooded with water at one season of the year and obstructedwith ice at another. Itwill first be described in connection with allthat is necessary to a full understanding thereof, and then clearlypointed out in the claims.

In the drawing, Figure 1 is a perspective view, and Fig. 2 is a sideelevation when the gate is fastened down.

A A represent fence-posts, each in two pieces. The lower piece A is sunkinto the ground, and has grooves a a at right angles to one another, andat a different elevation. The upper piece A has a tenon which turns on apivot fastened across the groove a. B B are the rails which are attachedto upper sections A to form a panel, and may be made of board alone, ofiron alone, or partly of each. C G are bars pivoted to the sides ofupper sections A while D D are pins or stakes which are also pivoted tothe inner sides of the same post section.

when the whole is secured firmly by the stakes or pins D D.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, isq 1. The posts A jointed at a, the pivotedbars 0 0, sections A A and stakes D D, combined to form a flood-fence,as described,

2. The bars 0 O pivoted to sides of upper sections A, and locking in thegrooves a a of lower sections A, as and for thepurpose set forth. g
